This means sensitive government, financial, and critical infrastructure data encrypted with current standards (RSA, ECC) is already at risk, even before quantum computers reach full capability. The US government has begun a transition to post-quantum cryptography (PQC), but the pace is insufficient given the breadth of systems requiring migration. Failure to act urgently exposes national security secrets, personal data, and critical infrastructure controls to future decryption. This is not a theoretical future threat — the clock is already running.","**Immediate actions:**\n- Conduct a full cryptographic inventory to identify all systems relying on RSA, ECC, or Diffie-Hellman encryption.\n- Begin piloting NIST-approved post-quantum cryptographic algorithms (e.g., CRYSTALS-Kyber, CRYSTALS-Dilithium) in non-critical systems.\n- Classify and prioritize sensitive long-lived data (state secrets, PII, financial records) for urgent re-encryption or protection.\n\n**Long-term improvements:**\n- Develop and execute a formal PQC migration roadmap with clear milestones across all federal agencies, states, and critical infrastructure sectors.\n- Adopt crypto-agility principles in system design so cryptographic algorithms can be swapped without full system overhauls.\n- Mandate PQC readiness requirements in procurement contracts for government IT vendors and supply chain partners.\n\n**Detection & Monitoring measures:**\n- Monitor for anomalous bulk data exfiltration that may indicate 'harvest now, decrypt later' collection campaigns.\n- Establish continuous logging of cryptographic protocol usage to detect reliance on deprecated or vulnerable algorithms.\n- Implement threat intelligence sharing between federal agencies and critical infrastructure operators regarding quantum-enabled adversary activity.",[12,13,14,15,16,17,18,19,20,21],"NIST SP 800-208 (Post-Quantum Cryptography)","NIST FIPS 203\u002F204\u002F205 (PQC Standards)","NSM-10 (National Security Memorandum on Quantum Computing)","NIST CSF 2.0 - Protect (PR.DS Data Security)","CIS Control 3: Data Protection","CIS Control 16: Application Software Security","GDPR Article 32 (Security of Processing)","FISMA 2014 - Federal Information Security Requirements","ISO\u002FIEC 27001:2022 A.8.24 (Use of Cryptography)","ITIL Service Transition – Change Management for Cryptographic Upgrades",{},"published","2026-10-08T12:21:47.09919+00:00","2026-10-08T12:21:46.771+00:00",{"id":7,"url":27,"slug":28,"title":29},"https:\u002F\u002Fcyberscoop.com\u002Fquantum-computers-could-break-todays-encryption-washington-needs-to-prepare-now\u002F","quantum-computers-could-break-today-s-encryption-washington-needs-to-prepare-now-53a98b","Quantum computers could break today’s encryption.
